请在C＃.net中提供嵌套列表的示例

Question

How can i add list to another list, eg:

List<string> list = new List<string>();

I want to add this list to another list, something like:

List<List> list2 = new List<List>()

Answer 1

var list1 = new List<string>();
var list2 = new List<string>();
var parentList = new List<List<string>> {list1, list2};

Answer 2

Create nested classes, and in each class a property of type List(Of xxSubClassxx)

a vb example would be:

class list1

 property list as new List(of xfirstlist)

 class xfirstlist

   property list2 as new list(of xSecondList)
   class xSecondList

   end class

 end class

end class
